CX1HSM CRYSTAL
10 kHz to 600 kHz
Miniature Surface Mount
Quartz Crystal for Series Oscillators
DESCRIPTION
The CX1HSM quartz crystal is a high quality tuning fork
resonator for use in Series (two cascaded inverters)
oscillators. The CX1HSM is hermetically sealed in a rugged,
miniature ceramic package. The CX1HSM crystal is
manufactured using the STATEK-developed photolithographic process, and was designed utilizing the
experience acquired by producing millions of crystals for
industrial, commercial, military and medical applications.
Maximum process temperature should not exceed 260OC.
